Which saw to cut chipboard with a jigsaw. How to cut smoothly with a jigsaw: recommendations

An electric jigsaw is the most convenient and universal tool For complex work on wood. With its help, you can produce artistic carvings, prepare various parts for carpentry and solve other problems.

Operating procedure

To get best result work, you need to know how to cut correctly with a jigsaw.

The material being processed must be securely fastened. Poor workpiece fastening is one of the main causes of errors when cutting. The jigsaw can jump off, go off the markings, or even go in an arc. By the way, if the jigsaw cuts crookedly, check whether the direction of the cut coincides with the direction of the fibers. If this is the case, then it is better to make a cut circular saw.
When it becomes necessary to make a cut on the inside of the workpiece, you should first drill a hole at the starting point.
When working with the tool, do not use much force. Electric tool cuts wood quite well and without excessive pressure. If you attach serious efforts To advance the jigsaw, the saw and motor become very hot, and the risk of breakdown increases. Besides, overpressure- the main cause of chipping.
When cutting hard rocks wood, it is advisable to add a little machine oil to the canvas.
Sometimes you have to work at low speeds. In this case, it is necessary to take frequent breaks from work, as the saw becomes very hot.

Accuracy problems

Let's look at how to cut smoothly with a jigsaw:

The object to be processed must be securely fastened. Moreover, in such a way that it would be convenient to make the cut.
In cases of particular uncertainty or for greater guarantee of accuracy, it makes sense to use guides. When making straight cuts, you can use it as a guide. wooden block, fixed along the marking. If the cut shape is complex, then the situation becomes more complicated. In this case, you can use patterns, if any, or you will have to reduce the speed of work by more carefully guiding the jigsaw.
One of the options why a jigsaw cuts crookedly is problems with the saw. It may be dull or have chipped teeth. If you notice that the jigsaw literally turns itself wherever it likes, inspect the saw.
Jigsaw failure. For example, if the motor runs jerkily, the likelihood of a crooked cut increases sharply. Likewise, other mechanism failures can lead to a decrease in accuracy. Similar problems difficult to fix on site, as it requires diagnostics and possibly repairs.
Finally, the accuracy of the work is greatly influenced by the skill of the performer. If you are a beginner carpenter, do not be discouraged by periodic failures: accuracy comes with experience.

Chips

Another serious question- how to cut with a jigsaw without chipping? These are usually formed:

when pressing the instrument excessively;
when working on thin material near edges without reinforcing stops;
when using unsuitable (worn) saws.

Avoid these actions and you will reduce the likelihood of chipping to a minimum. Also, some models allow the use of special anti-splinter inserts for jigsaws.

The file must be placed close to the cutting line. The guide is compressed with the platform side. After this, they begin cutting.

The tool moves forward smoothly and the platform is carefully controlled. The platform and guide should move closer to each other so that nothing moves. The sawn-off part must be carefully held with a few centimeters remaining to the end. Then the part will not break off.

What to do if you have problems with accuracy

The main requirement is reliable fastening of the material for which processing is required. In addition, cutting should be convenient for the person himself.
It is better to use guides if there are serious doubts that a person will cope with the work. For example, a block of wood will be an excellent guide for straight cuts. It is simply secured along the markings. It is much more difficult when the shape of the future product is quite complex. Then the use of patterns is recommended. Otherwise, the speed of work will have to be reduced so that the result is more accurate.
Problems with the saw are one of the most common problems during cutting. There is a possibility of chipping and dullness. It is better to inspect it if it is noticeable that the instrument is moving strongly to the side.
If there are jerks, there is a possibility that the cut will move to the side. Other failures in the instrument also lead to a decrease in accuracy. It is recommended to begin eliminating such problems immediately, on the spot.
The skill of the performer himself also affects the accuracy of the final work.

Professional secrets

It is necessary to check how firmly the canvas is fastened.

This mechanism may have its own characteristics depending on the manufacturer.

To work with any cutting tools, the fastening of the blade, its general position, is really important.

A useful device will be one that is responsible for removing sawdust. Its operating principle is very simple. There is a flow of air from the fan cooling the motor.

It is used to remove debris. The removal system makes the cut line more visible to the master's eye.

The drill can be easily changed when cutting holes using a technique called "pocketing". To do this, just tilt the jigsaw forward, then the rounded tips will rest on the surface being cut.

The blade should be positioned above the future cutting line with maximum accuracy. You need to lower the support saw horizontally, and then continue to practice.

For such work, marks are first made inside the material, and then, following them, the tool itself is drawn. If the shape is square or rectangular, the blade is pulled back slightly before the craftsman moves the tool to the next side. And this is how all four are processed.

The use of plunge cutting is permissible if it is impossible to create holes of the required dimensions. To do this, the jigsaw tilts forward until the file reaches the workpiece. Gradually during this process a through hole appears.

What else you need to know about working with a jigsaw

At its core, this device is a regular saw, only equipped with an electric motor. It is recommended to take it for carpentry work if it is necessary to cut surfaces with wide, smooth sides.

In this case, the instrument itself remains in place. Movement is organized only by the material that needs processing.

The cut is made from the back side, then its characteristics will please you.

Machine oil for lubrication is needed if you are working with metal or tiles.
Cold water should cool the cut line when processing metal.
Personal protection cannot be provided without glasses and gloves.
Using a jigsaw, plastic is processed only from the rear, otherwise it is impossible to obtain an even cut.

A special plate is attached to the support sole of the jigsaw; it allows for greater accuracy. This makes the saw blades move smoother over the surface. Any will be cut evenly.

About the types of instruments

First of all, they can be professional or household. Professional means that the device will have more power. It is usually 580-720 W. But for household ones it is less, from only 320 watts. But this is quite enough for a small amount of work at home.

The higher the power of the tool, the thicker the material it can handle without problems.

Any type of tool can handle creating holes up to 15 mm. But we must take into account that jigsaws, which have the lowest speed of 1000 rpm, cannot even cope with plastic.

Jigsaws are sometimes divided into groups depending on how the saw is mounted on them. For example, for a shank with a hole, smooth or cross-shaped. The last two types have become the most common because they are best suited for home tools.

Design and its features

Each jigsaw has a so-called support sole. It always rests on the part that needs to be sawed. Due to this, the accuracy of work is noticeably increased.

The soleplate can be easily rotated to make bevel cuts. Some manufacturers produce in which the main tool is fixed only at a certain angle.

The file acts as the main cutting tool. Tooth spacing, sharpening method, size, shape, materials - literally every model has its own. 75, 85 and 100 millimeters are the most suitable lengths if you need to cut materials of low density. The saw step size also becomes a fairly important parameter.

Metal requires a pitch of 12 millimeters.
U wooden products it is from 2.5 to 4.

About additional accessories

Special effort to obtain maximum result not required. The tool can work as a separate device, without any additions. But there are parts that can improve the performance of a regular jigsaw.

You can learn how to cut with a jigsaw without chipping from the video:

An electric jigsaw is a device with which you can cut plywood of different thicknesses, as well as cut out various kinds figurines. Let's try to figure out how to properly cut plywood with a jigsaw, and let's start with the fact that the main thing here is strict adherence to safety precautions!

Therefore, before starting work, it is necessary to take care of such protective equipment, How:

glasses;
gloves;
special oil.

Basic rules for cutting plywood with a jigsaw

For smooth cutting, you must adhere to the recommendations below.

At the very beginning, secure the plywood firmly.
Start sawing across the grain. If you do this lengthwise, cutting will be much more difficult.
Do not put pressure on the jigsaw. Otherwise, the device will heat up and may even fail.
If the plywood has increased strength, then coat it tightly with oil. This will make the work much easier.
Do not operate the jigsaw at low speed for too long, otherwise the engine may overheat. Upon completion of work, clean the tool and lubricate it.

Other process features

We continue the conversation about how to cut plywood using electric jigsaw. If you plan to cut into the material round hole, then first make a small hole and place it in hacksaw blade. You can also use plunge sawing if the previous method does not work.

Pay attention! A jigsaw is also suitable for cutting bevels. Here you can additionally secure the guide so that you can cut smoothly. To avoid chipping, place the plywood face down.

Using an electric jigsaw to cut plywood, you won't need to use any additional accessories. However, they - devices - can still be used to make the work easier and more comfortable.

If you are working with plywood of significant thickness, then use a special sawing table (this way you can work more accurately). Finally, if you are working with material of different thicknesses, then use replaceable inserts that are attached to the tool.

As a result, we note that a jigsaw can be either with a pendulum stroke or with a regular one. If the material is thick, the stroke should be normal. In this case, the plywood itself must move vertically and be cut as it moves.

Today we will tell you what affects the quality of sawing, how to saw off chipboard evenly and cleanly, and also how you can saw with a guide and without a guide with a regular circular saw.

We will show it using a hand-held circular saw as an example, but this does not affect the sawing techniques in any way, the difference is only in minor details. You can get similar quality cuts with a cheaper tool if you follow our advice.

What affects the quality of chipboard cutting?

IN in this case We will be sawing chipboard, this is the most capricious material for sawing, because it has longitudinal and transverse layers, quite delicate and thin veneer. But on the other hand, it has a hard adhesive base, which will also interfere with us.

Saw blade. How to choose it?

When cutting chipboard, the saw blade must simultaneously cut cleanly and be durable, because the properties of the glue are very close to glass and dull the tool itself quite quickly. Therefore, in the process cutting chipboard you need to choose enough good wheels to cut with them without loss of quality for a long time.

What is the difficulty of sawing with a circular saw with discs?

If we look at the cut of the workpiece, we will see that it is full of burrs, because “by hand” it is practically impossible to guide the saw straight through the cut.

On the saw blade there is a difference in height between the body of the saw itself and the sawing part - the tooth. Due to this distance, the disk has the ability to direct its position in the cut. Accordingly, as soon as it changes its geometry, the rear teeth begin to hit the chipboard workpiece and leave marks on it.

It is important to place the workpiece face down. Why?

The disk rotates from bottom to top; it cuts the pile of the workpiece upward onto the base. Thus, from below, on front side, we always have a clean surface. Problems begin to form at the top, where the teeth exit the workpiece. This is how explosions, chips, and piles happen.

How to minimize them, or avoid them altogether? There are several simple tricks and we will tell you about them now.

Technique 1. Cutting along the guide

We install a guide (rail) on the workpiece, set the sawing depth and make the cut. As you can see for yourself, even on outside There are no chips or explosions in our chipboard workpiece. The cut itself was smooth with no signs of scoring or side waves. Why is there such a difference?

What is the merit of the guide?

When we saw with a disk, we inevitably move the saw, the so-called “iron movement” is obtained. That is, when we move our hand, we constantly move the saw to the right and left. A guide that has a hard edge allows you to avoid this.

Accordingly, when we guide the saw along the guide, it does not move and saw blade works smoothly without changing its position. The result is an ideal line parallel to the guide.

What to do if you don’t have a hand-held circular saw and guide?

You need to make the guide yourself. We find regular profile, you can take the rule, any smooth slats, the main thing is that its geometry is smooth.

We measure the distance from the saw blade to the edge of your chipboard blank. We attach the guide to the workpiece using any clamp and begin cutting.

The main thing in the process is to constantly press the saw against the guide. That is, your hand should always guide the saw towards the homemade tire.

After cutting, you will get an almost perfect cut, the cut line is barely visible. We performed the cut very well, the cut itself is clean, no side marks are visible on it. With the exception of a small pile on the back side of the workpiece.

Where did this lint come from, since we were working with a guide (tire)?

The purchased cutting bar has a special plastic protective tape. This tape prevents the pile from rising and the saw cuts it. In this case, we didn’t have this tape, so we got this lint on the surface.

What to do with the pile in this case?

There are two options:

1. Take regular masking tape. It is glued to the place of the cut, markings are made on it and sawed together with masking tape. The tape holds the ingrown in place and when cutting we get everything clean.

2. Just drive the saw blade more slowly. That is, if you do the same thing with a slower feed, then there will be much fewer chips.

Technique 2. “Reverse cut.”

The first pass is performed in an unusual manner - in reverse. That is, the circular saw rotates as the workpiece is fed. We set the minimum cutting depth, turn on the saw and move backwards rather than forwards.

If you have a regular saw, then simply fix the saw with minimal overhang beyond the base. The point of the first pass is that the blade, moving along the guide, only catches our workpiece. We need a small groove on the chipboard.

Having made the first - trimming cut - you will make sure that there are no chips with such a feed (backwards). The surface is perfect!

Now we will set the saw to full depth and cut the workpiece along this groove with a regular cut - forward feed. We will get two cuts per workpiece. No wave cuts, arson, nothing - perfect quality!
